I was switching to a new bank and everything works fine there. Still I cannot find any differences in settings. Weirdo…

Try placing a trigger in grid record mode on the offending track hit play, remove trigger and see if that solves it.
I have a suspicion about tracks/slots getting hung up on the old banks settings and not being updated until triggered in the new bank… This may or may not be the problem here.
